When generating a CSR from the console, for some reason my AltNames varible is not inserting into my generated CSR.

I've had so many problems with the Admin Console that I'm trying to get it to work right from the CLI.

I've looked through so many threads but can't seem to figure out why it's not generating the CSR with my AltName.

Code:
root@MAIL:/opt/zimbra/ssl/zimbra/commercial# /opt/zimbra/bin/zmcertmgr createcsr comm -new -subject "/C=US/ST=N\/A/L=N\/A/O=Zimbra Collaboration Suite/OU=Zimbra Collaboration Suite/CN=external.MAIL.com" -subjectAltNames "internal.org.MAIL.com"
** Generating a server csr for download comm -new -subject /C=US/ST=N\/A/L=N\/A/O=Zimbra Collaboration Suite/OU=Zimbra Collaboration Suite/CN=external.MAIL.com -subjectAltNames internal.org.MAIL.com
